What this misses is a use case of indexed searches where resulting index
value is used beyond the loop itself. By changing context of variable
declaration, you make variable inaccessible outside of the loop.
I would say it's exactly the purpose of this proposal.
To decrease scope of visibility so the index variable with short name
cannot be misused for different purpose.
